  • Method of drawing single crystals
    Patent number: 6126742
    Abstract: In a method of drawing single crystals from a body of highly pure polycrystalline material molten by inductive heating, a solid body of the polycrystalline material is first heated by direct induction heating at a frequency >200 KHz to increase its conductivity and is then further heated by direct induction heating at a frequency <20 KHz to melt the center of the body of polycrystalline material to form a molten pool contained by a marginal solid zone of the polycrystalline material from which the single crystal is drawn.
    Type: Grant

    Assignee: Forshungszentrum Karlsruhe GmbH
    Inventor: Leopold Barleon
  • Nuclear reactor installation including a core catching apparatus
    Patent number: 4121970
    Abstract: A nuclear reactor installation includes a core catching apparatus for containing the components of a nuclear reactor core during a core melt-down accident which comprises a container provided with means for preventing the mixing of the metallic portion of the core melt with water thereby to avoid formation of explosive gases and spreading of radioactive compounds by an explosion following such core-melt-down-accident.
